Sigh... these youngsters! History lesson: ON Completed coding sheets are output from programmers (perhaps their only valuable output).
After exhaustive "desk checking" (olde English for "a complete and utter waste of time", since programmer's are always perfect), the coding sheets were then input to the keypunch department which output punch cards. The punched cards were then input to computer operators (well, at least one of their known inputs besides coffee and candy bars and God knows what else on 3rd shift) who loaded them as input into punch card readers (one hopes good old 2540's- not those newfangled 3505 optical card readers that were always jammed by the slightest dust mote, of which card provided aplenty). Provided that one of the F1, F2, or BG partitions was open when the punched cards were read by the punched card reader, and the computer operator had the appropriate UPSI switches set properly, and had uttered the correct mystical incantations at the right time, the computer would process the punched cards into its core memory and execute them as a program, or supply them for a program's input needs. History lesson: OFF Hey... if they had optical card readers, why weren't there any optical card punches?
